Abstract: The laser amplification apparatus is provided with a plurality of plate-shaped laser medium components (M1 to M4) which are disposed to be aligned along a thickness direction, and prisms (P1 to P3) which optically couples the laser medium components. Each of the laser medium components is provided with a main surface to which a seed light is incident, and a side surface which surrounds the main surface. An excitation light is incident from at least one side surface of a specific laser medium component among the plurality of laser medium components. The excitation light is incident through the prism to a side surface of the laser medium component adjacent to the prism.

Abstract: Provided is a laser device including N semiconductor laser array stacks, a prismatic optical system that shifts optical axes of luminous fluxes respectively output from the N semiconductor laser array stacks so as to decrease intervals among the luminous fluxes, and an imaging optical system that causes the luminous fluxes to be condensed and deflected for each luminous flux. The imaging optical system causes the luminous fluxes to be deflected so that the luminous fluxes overlap each other at a predetermined position and generates a light-condensing point of the luminous fluxes between the imaging optical system and the predetermined position.

Abstract: An optical amplification device includes: a laser medium that amplifies input light to generate output light; an excitation light source that supplies excitation light used for amplifying the input light, to the laser medium; a resonator that includes a pair of first optical elements and disposed to optically face each other with the laser medium interposed between the first optical elements and that resonates generated light generated in the laser medium through the supply of the excitation light; and an optical switch disposed on an optical path of the resonator between the pair of first optical elements.
